Floating Clamshell Dredgers

ROHR-IDRECO floating clamshell dredgers are designed to extract sand and gravel from 10 to 60 or even 90 metres below water level. All dredgers are custom-built to the requirements of each deposit and the needs of every customer. Customers can choose among various components for on-board processing, such as double or single-deck screening machines, crushers, fine sand recovery, conveyor belts or hydraulic transportation to site. Two types of hydraulic motor grabs manufactured in-house complete the package and make the dredger an efficient tool for every purpose.
